Rockdrill Repair Shop
The rock drill repair shop should be a clean area equipped
with all the usual filters’ tools, work benches, component
cleaning tanks and a hydraulic press. Your work shop
should have the following items:
PHQ Test Bench – custom designed and made to test
torque generated by the drill and leg pressure. Every
drill that is repaired in the drill shop should be “run-in”
on the test bench using the spring loaded device that
allows the drill to be run under load and leg pressure
